A low‐power analogue readout circuit for quanta image sensors is reported. A modified charge‐transfer amplifier is used in column‐parallel circuits to reduce the internal readout circuit power 50‐fold compared to the state of the art, and will achieve 2 mW total power dissipation (all columns) when applied to a 1 Mpixel binary image sensor operating at 1000 fields per second.
